Why is my Vauxhall Zafira Life's engine making a ticking noise?

I've noticed that the engine of my Vauxhall Zafira Life is making a ticking noise when it's idling. It's not very loud, but it's definitely noticeable. Any idea what could be causing this and how to fix it?

The ticking noise from the engine could be due to a lack of oil or dirty oil. Check your oil level and condition and change it if necessary.

It could also be a sign of low oil pressure or a faulty oil pump. Have a mechanic check and replace the oil pump if needed.

Another possibility is that there's something loose or damaged in the engine or exhaust system. Have a professional inspect and tighten or replace any parts if necessary.
